As usual, the last version of Xcode that is compatible with macOS 11 Big Sur (Xcode 13.2.1) only contains the macOS 12 Monterey SDK. This can confuse most open source software which doesn't know how SDKs work. You can avoid most problems if you also install the Xcode 13.2 version of the command line tools (there was no 13.2.1 version of the CLT) since the CLT contains both the macOS 11 and 12 SDKs and MacPorts will tell most ports to use the macOS 11 SDK from the CLT.
